====== reverse proxy ======

===== reverse proxy =====

<code>
ProxyRequests Off
SSLEngine On
SSLProxyEngine On

ProxyPass / https://example.com/    <-- note trailing slash!
ProxyPassReverse / https://example.com/    <-- note trailing slash!
</code>


===== app behind location (folder) =====

To achieve:
  * http://example.com/app1  --> http://service1.local:8081
  * http://example.com/app2  --> http://service2.local:8082

It is complicated. Needs rewriting of content body and fix all links to local resources.
It is better to make 1:1 reverse proxy and configre remote service to work under location (folder):

  * http://example.com/app1  --> http://service1.local:8081/app1
  * http://example.com/app2  --> http://service2.local:8082/app2

If not possibe to reconfigure remote service server you can try to use ''proxy_html'' module which can rewrite content and fix URL mappings.

File ''/etc/apache2/mods-available/proxy_html.conf'' contains example:
<code ini>
# ProxyRequests Off  <-- this is an important security setting
# ProxyPass /my-gateway/ http://some.app.intranet/
# <Location /my-gateway/>
#       ProxyPassReverse /
#       ProxyHTMLEnable On
#       ProxyHTMLURLMap http://some.app.intranet/ /my-gateway/
#       ProxyHTMLURLMap / /my-gateway/
# </Location>
